The Colombian Navy intercepted an unmanned semi-submersible submarine on Tuesday 60 nautical miles from the mouth of the Naya river that flows into the Pacific Ocean. The vessel is believed to have been intended for drug smuggling purposes, Colombia Reports informed.

Navy Commander Carlos Delgado said that the submarine features 18 meters in length, three meters in width and two propelling motors made of fiberglas, having capacity to “reach the Mexican coast without refueling, and has a fuel capacity of around eight days”. The vessel can accommodate three or four crew members.
